In which group of plant kingdom gametophyte is depend on sporophyte ?

Options

A. Algae
B. Bryophyta
C. Moss
D. Gymnosperm

Answer

To answer the question "In which group of plant kingdom is the gametophyte dependent on the sporophyte?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plant Life Cycles**:
- In the plant kingdom, there are two main phases in the life cycle: the gametophyte phase (haploid) and the sporophyte phase (diploid).
- The gametophyte produces gametes (sperm and eggs), while the sporophyte produces spores through meiosis.

2. **Identifying the Groups**:
- The groups mentioned in the options are likely to be different categories of plants, such as Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.

3. **Analyzing Each Option**:
- **Option 1: Bryophyta (Mosses)**: In Bryophytes, the gametophyte is the dominant phase, and the sporophyte is dependent on the gametophyte. Thus, this option is incorrect.
- **Option 2: Pteridophyta (Ferns)**: In Pteridophytes, the sporophyte is dominant, but the gametophyte is independent and free-living. Hence, this option is also incorrect.
- **Option 3: Gymnosperms**: In Gymnosperms, the sporophyte is the dominant phase, and the gametophyte is dependent on the sporophyte. This is the correct option.
- **Option 4: Angiosperms**: Similar to Gymnosperms, Angiosperms also have a dominant sporophyte phase, but the question specifically asks for a group where the gametophyte is dependent on the sporophyte.

4. **Conclusion**:
- The correct answer is **Gymnosperms**, where the gametophyte is dependent on the multicellular diploid sporophyte.

### Final Answer:
**Gymnosperms**
